How often should calibration be performed on radar and lidar devices?

Calibration of radar and lidar devices is critical to ensure accuracy and reliability in speed detection. The requirement to calibrate these devices daily or as dictated by agency standards acknowledges the variations that can occur due to environmental factors, equipment wear, or changes in operational conditions.

Regular calibration helps maintain the integrity and accuracy of speed measurements, which is essential for legal enforcement and safety on the roads. Different agencies may have specific criteria or guidelines that dictate the frequency of calibration based on the volume of use, the specific application of the device, or regulatory directives.

While calibrating before a shift or weekly might seem sufficient, these options do not account for the potential fluctuations in device performance that could occur throughout the day or week. Therefore, instituting a daily calibration routine or adhering to the necessary agency standards provides the best assurance of measurement accuracy and reliability.
